BUILDING-PARTITION.

Specification of., Letters Patent.

Application filed May 16. 1913.

Serial No. 767,990.

the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in partitions more especially intended for use in fire-proof buildings. In this last-named relation the partitions include plaster boards which form the foundation for the mortar and plaster which is applied to opposite sides thereof in order to complete the partition.

The special feature of my improvement consists in a clip for connecting the plasterboards to studs, preferably composed of metal which are usually employed in parti tions of this character. These studs may consist of channel bars or they may be flat, cylindrical or of any other desired or suitable shape that may be requisite, necessary or desirable in any particular case.

My improved clip in its simplest form consists of a pair of loops arranged in parallel relation, the same being formed from a single piece o'lf wire properly bent for the purpose, the said loops being arranged to straddle the plaster-boards on one side of the jointwhile the free extremities of the wire of which the clip is formed embrace the partition on the opposite side of the joint.

These clips may be employed to form joints.

where the plaster-board sections are arranged in alinement with each other or where they extend at an angle to each other, regardless of the degree of the angle. The portions of the clip consisting of the two terminal parts of the wire may be tied together by a smaller wire in order to give this part of the clip additional strength and security, wherever the conditions are such as to render this desirable or necessary.

While the simple form or unit of the clip is as just described, it will be understood that the clip may, consist of several pairs of double loops arranged at different angles and suitable for joining two or more partitions, as may be desired. In this case each pair of loops serves to embrace a building partition section on opposite sides, the clip being properly applied to the stud in order to connect the partition sections therewith. It should also be understood that these dew ble loops, as well as the extremities of the wire of whichthe loop clip is composed, may be off-set either outwardly or inwardly, as may be required. One occasion which may necessitate or render advisable such a construction is where the partition sections are either narrower or thicker than the stud with which they are connected. In this case the parts of the clip beyond the stud as the double loops or the terminal portions of the wire, are bent inwardly or outwardly as may be desired in order to form a structure for embracing the board section on opposite sides. These pairs of emln'acing loops or terminal clip portions are preferably so arranged that the loop parts must be additionally spread in order to receive the partition sections, so that the loop members may grasp or tightly engage the said sections on opposite sides.

Having briefly outlined my improved construction, I will proceed to describe same, in detail, reference being made to the accompanying drawings in which is illustrated an embodiment thereof.

In this drawingFigure 1 is a perspective view illustrating the simple form of my invention, the stud and plaster-board sections being indicated by dottedlines. Fig. 2 is a fragmentary side elevation of a skeleton wall composed of studs and plasterboard sections connected by my improved clips, the parts being shown on a smaller scale than in Fig. 1. Fig. 3 is a section taken on the line 3-3, Fig. 2, looking downwardly. Fig. 4: is a section taken on the line 44, Fig. 2, looking downwardly. Fig. 5 1s a section simllar' to Flg. 3 but showing the united plaster-board sections of difl'er- Patented May 12, 1914..

. ing to four different partitions, all of said sections being connected with a stud by reason of the multiple loop form of my improved clip. Fig. 10 is a perspective view of the same- Fig. 11 is a horizontal sectional view, cutting the plaster-board sections and stud and looking downwardly on still andther form of my improved clip."

Fig. 12 is a side elevation of the same,-being a View looking in the direction of arrow 12, Fig. 111. Fig. 13 is a view similar to Fig. 11 and showing a slightly modified form of construction. Fig. 14 vis a side elevation of the construction shown in Fig. 13, being a view looking in the direction of arrow 14, Fig. 13. Fig. 15 is a section similar to Figs. 11 and 13, showing still another form of my improved fastening clip. Fig. 16 is a side elevation of the same, being a view looking in the direction of Arrow 16, Fig. 15. Fig. 17 is a section similar to Fig. 13, but showing a cylindrica1 form of stud. Fig. 18 is a side elevation of the same construction, being a view looking'in the direction of arrow 18, Fig. 17.

The same reference characters indicate the same parts in all the views.

Referring first more particularly to Figs, 1 to 4, inclusive, let thenumeral 5.,designate my improved clip considered in its entirety and consisting of a pair of double loops 6 formed from a single piece of wire and connected by a transverse part 7, which engages the stud 8, the part 7 connecting the upper members 9 of the two loops while the lower members 10 of the loops merge into extensions 12 adapted to embrace one of the plaster-board sections 13 on opposite sides, while the loops 6 embrace the adjacent plasterboard member 13 in the same manner. In

order to add additional strength and se-,

curity to the parts 12 of the clip, these parts may be tied by a piece of wire 14: which is preferably passed around the extensions adj acent the stud and below the transverse part 7- of the clip. As illustrated in the 15 which connects the two parts'9 and. 10

' ofeach loop 6. As illustrated in the drawvertical wall. It will of course be under- 2 stood that these clips are equally well adapted for use with the walls or ceilings horizontally disposed or arranged at any angle between vertical and, horizontal.- However, for convenience of description it is assumed in this specification that the clips are applied to vertical walls and in the description of the various forms of clip the terms employed are used with this understanding, though it-must also be understood that these terms are not limitations.

In erecting partitions where my improved clips are used, it is assumed that the studs 8 are properly secured at their opposite extremities which, in vertical partitions, will be at the top and bottom, The clips are then applied to the stud by passing the vertical loops 6 on opposite sides of the stud and moving the clip until the transverse part 7 engages the stud on one side. When this is done, the two loops 6 will extend on one side of the stud while the two extension parts 12 of the clip will project on the opposite side of the stud. The plaster-board sections are then applied and moved toward the stud, one section being passed between the loops 6 and the other section between the extensions 12 of the clip. In this manner the various sections of which the skeleton partition is to be composed are connected with the stud. Of course where a number of clips are usedat each extremity of a plaster-board section, all of the clips to be used in connection with one extremity of any section must be applied before the plasterboard section on the opposite side of the stud is put in place.

Referring now to Fig. 5 of the drawing, the construction is exactly the same, except that the plasterboard sections are of different thickness and for convenience of reference will be respectively designated by the numerals 16 and 17, 16 designating the thicker section. In this case the section 16 is also somewhat thicker than the stud 8 and for this reason the loops 6 ofthe clip are spaced farther apart than the plasterboard;section-embracing extensions 12. -In this view the sections 16 and 17 are so arranged that they are flush on one side of the partition, there being an off-set 18 formed in the loop to make up for the inequality of thickness of the sections, on the opposite s1 e.

In the form of construction shown in Fig. 6, the two loops 6 are connected by a transverse part 19, the opposite members of the loop merging by bends 20 into laterally-arranged loop parts 21, which embrace the opposite edges of the stud 22 which in this case is of the flat type of stud and formed wider than the thickness of the plasterboard partitions 13.- Beyond the loop parts 21 are located the extensions 12 which engage the section 13 on opposite sides in the same manner as in the construction shown in Figs. 1 to 1, inclusive, It will be observed that in this form of construction the trans verse part 19, connecting the two vertical members 6 of the clip, does not engage the stud, the opposite edges of the latter being directly in contact with the two laterally-arranged loop parts 21 which are located between the loops 6 and the extensions 12, which engage the plaster-board sections on opposite sides. In this form of construction it should be understood that when the plaster or mortar is applied to the skeleton partitions on opposite sides, this layer of mortar will be of sufficient thickness to conceal the lateral loop parts 21.

The form of clip construction shown in Figs. 7 and 8 is similar to that illustrated in Fig. 1, except that the parallel clip extensions 12 extend at right angles to the direction of a loop part 6 by reason of the right-angular arrangement of the plasterboard sections 13.

In the form of construction shown in Figs. 9 and 10, the clip, while of the same general type as shown in the other forms of con struction, is somewhat more complicated and includes three pairs of loops 6, each of substantially the same construction as shown in Fig. 1 and arranged to embrace three plaster-boardsections 13,'tlie extensions 12 of'the clip being arranged to embrace the fourth plaster-board section 13. In this case, the four plasterboard sections form parts of two walls intersecting at right angles. The two loops 6 of one pair are connected by a transverse part 7, which engages the stud 8 in the same manner as in Fig. 1, while the two pairs of loops 6 embracing the sections 13 which are in alinement with each other have their members connected in each case by a transverse part 23, which is arranged in the same plane as the transverse part 7. In this form of construction, the clip is also made of a single piece of wire bent to form the various loops arranged as heretofore explained.

In the form of construction shown in Figs. 11 and 12, the plaster-board sections 13 are of the same thickness and both are thicker than the stud 8, thus necessitating the formation of off-sets 24, where the loop members 6 merge into a loop part 25, which in eludes opposite side members and a part 26 connecting the side members and engaging the stud on the side extending at right an gles to the-surfaces engaged by the two side parts of the loop member 25. The neces sityfor the two off-sets 24 in this case arises from the fact that the stud is centrally arranged with reference to the thickness of the partition board sections instead of being so,

located that it would be flush with the surfaces of the sections on one side. In the last-named case there would, of course, be

no necessity for two off-sets but the one offset would be of double the magnitude of either oft-set, as shown in these views.

In the construction shown in Figs. 13 and 14, the clip is precisely of the form shown in Figs. 11. and 12, except that between the loops 6 and the extension parts 12, inwardly bent loop parts 27 are formed, the said parts being adapted to engage a stud directly below the opposite side parts of the loop member 25.

In the form of construction shown in Figs. 15 and 16, the two loop parts 6 are connected by a transverse part 7, while the lowe part 10 of each loop merges into an inwardly bent loop part 27 which is substantially the same as the corresponding part in the construction shown in Figs. 13 and 14. In the construction shown in Figs. 15 and 16, the stud is embraced on opposite sides by the two parts 27, the transverse parts 7 being located between the stud and one of the plaster-board sections 13.

In the form of construction shown in Figs. 17 and 18, the clip is exactly the same as shown in Fig. 1, except that the part which connects the two loops 6 at the top is curved, as shown at 28, by reason of the fact that the stud 29 is cylindrical.- In this case the adjacent edges of the plaster-board sections are preferably curved, as shown at 29, to conform to the curved adjacent surfaces of the cylindrical stud. These edges, however, may be plain or straight, it desired, inasmuch as it is not necessary that the edges of the plaster-board sections should closely fit or engage the studs.- In fact, it is preferable that these edges should be removed somewhat from the studs in order that during the operation of applying the plastering mortar the latter may enter the spaces between the studs and plasterboard edges, whereby the mortar is an chorcd. This arrangement also has a tendency to prevent cracks in the plaster.

From the foregoing description, the use of my improved construction will be readily understood.

In the drawing, I have illustrated a num berof the various forms of construction of 1 of studs used, necessitate corresponding modifications in the style of clip, as has been quite fully disclosed in the drawing and the detailed description heretofore given. Attention should, however, 'be called to the fact that the horizontal edges of the plastereconomical.

used in connection with the vertical edgesof the plaster-board sections, the only difi'erence being one of arrangement. in Flg. 2, the loops 6 of the clips engage the upper plaster-board sections, whilethe extensions'12 engage the lower sections of the skeleton partition.

Attention is called to the fact that while I have used the term wire in describing.

the material of which my improved clips are composed, it must be understood that the cross sectional rea of the material employed is immaterial as it may be desirable in many instances to use fiat material in the making of these clips, though it is believed that the .form of construction illustrated in the drawing will, under ordinary circumstances, be preferable as it is believed to be the most I will further state that while in partitions of the character described, metal studs are usually employed, it is under some circumstances practicable to make these partitions Without the employment of studs, the plaster-board or other sections being connected and supported by the use of my improved clips.
